驱避剂防治土栖白蚁研究初报

土栖白蚁是园林树木的重要害虫[1],以往大多采用挖掘蚁巢和药剂毒杀等方法防治,前者往往挖掘不尽,有时还出现人为分巢,促进繁殖;后者易污染环境,杀伤天敌,特别是抑制白蚁对园林生态的积极作用[2]。笔者根据白蚁主要生活习性及园林生态特点,于1996～1998年应用驱避剂进行防治园林土栖白蚁试验,以达到既保护园林树木,又维护园林生态环境的目的。对防治土栖白蚁过去虽有报道[2,3],但应用驱避剂防治研究却尚属首次。现将初步研究结果报道如下,以供城市公园、森林公园及古树名木白蚁防治作参考。1　材料与方法1.1　试验地概况浙江省余杭市临平公…

Study on Control of Termites in Gardens Using Repellents

A field study for controlling termite damage to ornamental trees in gardens was undertaken in Linping Garden,Yuhang,Zhejiang,China from 1996 to 1998. The approach to termite control was designed on the consideration of avoiding over interference to the garden ecosystem and the treatments were achieved by using repellents including 0.8% chlorpyrifos emulsion,2.5% LX gradual releasing granule and lime.The results showed that all treatments were effective at different levels against termite damage,with the best controlling from chlorpyrifos treatment.In the latter case,the treated trees were totally free from termite damage for three years after treatment,while termite activities were not interfered on the ground one meter away from the trees.
